Steve-OWho peed on the red carpet?Just because you didn't get nominated for an Oscar, does not mean you should urinate on the red carpet.

This is a lesson one Hollywood type would do well to learn...

And no, it wasn't an animal who peed on their way into a pre-Oscars party. It was a human being.

The culprit? Jackass crazy dude Steve-O.

Mr O was on his way into The Key Club on Hollywood's Sunset Strip, when he unzipped his trousers and made like a life-sized fountain.

Just why he decided to trickle there is somewhat of a mystery, but knowing what those Jackass boys are like, it could have been a dare.

Or perhaps he just really needed to have a tiddle and couldn't make it to the loo in time?

Steve-OSteve-OSadly, the story does not end there, ladies and gentlemen (ladies might wish to look away now).

Not content with ruining the carpet, Steve then stripped off to his birthday suit.

We've got it all in the gallery above, so take a look for yourself... unless you're easily offended.
